I'MPROVEMENT INFCAR-COUPLINGS.

Specification forming part of Letters Patent No. 217,158, dated J uly 1, 1879; application filed February 15, 1879.

To all whom it may concern:

Be it known that I, JAMES B. SAFFORD, of the city of Buffalo, in the county of Erie and State of New York, have invented a new and useful Improvementin Oar-Couplings, of which the following is a specification, reference being had to the accompanying drawings.

My invention consists in forming the drawhead with pinseats having a vertical groove on the rear side, and in forming the couplingpin with two intersecting horizontal bores or cavities, in which is secured a rivet, the draw-.

head and coupling-pin being adapted to cooperate in the manner hereinafter more fully set forth. e

In the accompanying drawings, Figure 1 is a sectional elevation of two draw-heads provided with my improvements. Fig. 2 'is a top-plan view of one of the draw-heads. Fig. 3 is a bottom-plan view thereof. Fig. 4 is a cross-section in line as m, Fig. 1. Fig. 5 is a horizontal section in line 1 Fig. 1. Fig. 6 is a horizontal section, on an enlarged scale,

through the lower end of the coupling-pin preparatory to securing the stop thereto. Fig. 7 is a similar view, with the stop secured to the pin.

Like letters of reference designate like parts in the several figures.

A represents the body of the draw-bar, and B the head thereof. 0 is the mouth or cavity of the draw-bar, and D D the pin holes or seats, arranged in the upper and lower parts of the draw-head. E is the coupling-link, of ordinary construction; and F, a pallet, ar-

' ranged in the rear portion of the mouth of the draw-bar, for pressing the inner end of the a coupling-link against the coupling-pin, thereas to permit the stop h of the coupling-pin to freely slide therein.

The top portion of the upper pin-seat, D, is beveled or inclined forwardly, as shown at k, so that the coupling-pin can be tipped forward when raised to its highest position, as shown to the right in Fig. 1. In this position of the coupling-pin its heel or rear bottom portion is supported upon ofi'sets or shoulders Z Z formed on both sides of the groove 73 in the upper pinseat, D. y

The top portion of the groove i is enlarged, as shown at m, to accommodate the stop h when the coupling-pin is inclined forward, as above described.

The stop his composed of a rivet inserted in a horizontal bore or cavity, a, entering the lower end of the coupling-pin from the rear, and intersected by a similar horizontal cavity, 0, arranged at right angles to the cavity a, as clearly shown in Figs. 6 and 7. The rivet h is made somewhat longer than the cavity a.-

After the coupling-pin is inserted in the draw-head the rivet h is properly heated and driven into the cavity 12, whereby the inner end of the rivet is upset laterallyin the transverse cavity 0, and the rivet firmly secured in place.

- The front sides of the coupling-pin and of its seats D D, which serve as bearing-stir faces and receive all the wear, are in my im proved device left intact, and the width of the coupling-pin is increased to the full width of the openings in the draw-bars and links in general use, thus producing a stronger pin and with a greater wearing-face than any ordinary coupling-pin. The stop It on the rear side lies in the longitudinal direction of the openings of the common coupling-links and draw-bars, and a coupling-pin having a stop arranged in this manner will easily pass through any ordinary coupling-link or drawbar over the pilot of locomotives. Upon raising the coupling-pin and supporting it in a forwardlyinclined position upon the shoulders Z it is securely held in this position, and the draw-heads can be brought in contact Without causing the pin to descend, and couple the parts together, while by resting the pin upon the upper end of the pallet F the cars will be automatically coupled together as soon as the link enters the draw-head.

It is obvious that my improved couplingpin cannot be entirely withdrawn from the draw-head, thereby preventing the loss of the p ns.

I claim as my invention The combination, with a draw-head having its pin-seats D D provided with a vertical groove, 6, arranged on the rear side of the seats, of a coupling-pin provided with two intersecting horizontal bores or cavities, n 0, and a rivet, h, secured therein on the rear side of the pin, substantially as set forth.
